To find cons in a smartphone is easiest thing to be done. But not when it comes to the Samsung galaxy s7. It is almost impossible to find any problem in s7. The phone is the best looking smartphone in the market. The quad hd super amoled display is a treat to look at. 4 GB of ram is enough for s7 to run every games and tasks fluently. Also the phone is compact for a 5.1 inches display phone so it is easily disable with single hand . Battery life is good and even better is that it supports fast charging which helps to charge the phone to UpTo 50? with just 30 minutes of charge. Fingerprint sensor is bit slow compared to other lhones but accurate. One problem with fingerprint sensor is that you need to wake up the phone to read your fingerprint or tap on home button and then have your fingerprint unlock. Sound quality is best for the smartphone. Network signal is always full. No problem in this either. Also the mobile is ip68 water resistant so you don’t need to worry about taking your phone for a swim with you and taking underwater shots. Samsung has always been good at service so no doubt there. Overall s7 is a super phone. Recommended .
